Description

Current swift driver will encounter authentication issue if swift server has token timeout. It will be good if driver can automatically renew once it expired. We met HTTP 401 error when transferring a 100gb file to swift object store. Since the large file is chunked into 27 files, the server will ask each chunk for token inspection. If server has timeout and 100GB file transferring time is longer than this timeout, token will expire and the file transferring will fail.
